    • Electrofission of (sup 239) pu in the energy range 7-12 mev 

      Arruda-Neto, João Dias Toledo; Yoneama, Maria Lucia; Dias, Johnny Ferraz; Garcia, F.S.; Reigota, M.A.V.; Likhachev, V.P.; Guzman, F.; Rodriguez, O.; Mesa, J. (1997) [Artigo de periódico]
      The electrofission cross section of ²³⁹Pu(e,f) is measured between 7 and 12 MeV. The data are analyzed by means of the virtual photon formalism, assuming that E1, E2 (T=0), and M1 transitions are involved. Using known ...

    • Triton angular distributions from the /sup 7/Li([gama],t)[gama] reaction near threshold 

      Likhachev, Vladmir P.; Martins, Marcos Nogueira; Cruz, Manoel Tiago Freitas da; Arruda-Neto, João Dias Toledo; Geraldo, L. Paulo; Semmler, Renato; Dias, Johnny Ferraz (1999) [Artigo de periódico]
      Angular distributions of tritons emitted in the reaction ⁷Li(y,t)α have been measured for two photon energy intervals (6.4–6.7 and 8.5–9.0 MeV), and θt between 30° and 150°. Monochromatic photons from neutron capture ...
